14 Claims.

This invention relates to a fruit juice extractor.

An object of this invention is to provide anapparatus for automatically cutting the fruit, such as a citrus fruit, and then extracting the juice from the cut pieces of the fruit in one-continuous operation; the apparatus providing for the automatic loading of the apparatus which carries the fruit through the steps of its treatment .until the fruit Juice is eifectively extracted.

Another object of this invention is to provide an apparatus wherein the fruit, such as a citrus fruit, isautomatically engaged and carried over a knife to be cut at a predetermined angle and then the cut portions of the fruit are carried to an extracting mechanism for the extraction of all the juice from said pieces of the fruit, and wherein this operation is repeated automatically until the apparatus is stopped.

Particularly it is an object of this invention to provide a carrier for the fruit holders of a fruit extracting machine which rotates so as to carry the holders to a loading point where a fruit picked up in the holders, and then carry the loaded holders over a knife in the path of the rotary movement so as to cut the fruit in the holders. and then convert the rotary motion at in the holders to the action of a Juice extractor,

and then resuming the rotation of the carrier to carry said holders back to said loading position,

means being provided to adjust the relative positions of the fruit holders for the various steps of a fruit'juice extractor which is highly useful and simple in construction. Convenience of arrangement, lightness and comparative inexpense of manufacture are further objects which have been borne in mind in the production and development of the invention. I

We are aware that some changes may be made i in the general arrangements and combinations of the'several devices and parts, as well as in the details oi the construction thereof without de-' parting from the scope of the present invention as set forth in the following specification, and as defined in the following claims hence we do not limit our invention to the exact arrangements and combinations of the said device and parts as described in the said specification, nor do we con flne ourselves to the exact details oithe construction of the said parts as illustrated in the accomloading, cutting and extracting during the continuous movement of the apparatus.

A further object of this invention is to provide a carrying mechanism for the fruit holders of a fruit extractor which utilizes rotating drive to carry the holders around a substantially circular path from a loading position through a cutting position and to an extracting position, and from the extracting position back to the loading position, but converting said rotary movement into the driving of the apparatus being adapted for automatic control or coin control.

Another object of this invention is to provide D ying drawings.

With the foregoing and other objects in view,

which will be made manifest in the following detailed description, reference is had to the accompanying drawings for the illustrative embodiment of the invention, wherein:

Eorinstance in the present illusrelatively to the position of the holder units I5 tiation the" apparatus is used for extracting relatively to a awar orange juice from oranges. The orange it as shown in broken lines infFig'ures 2,14, 6 andZ;

' is held ina suitable hopper at thetopo'fthe apparatus. 1 Below the feed ope ing for the hopper 49 'is a dished platform 53 within iwhich the orange 5| is held stationary j' Thisplatiormf 53 is'narrower' than theusual dianieter'of'the" orange used in said apparatus so asto"allow the cups 23 travel over said platform WonJanarcuQ' ate upward path. This permits the extension of the lip il slightly upwardlyflthereby to provide a retainer lip for holding the oranges m t on ing 01! the platform 53.

The inner blade or knife ed gejfi curves inwardly toward the carrier to below the level oi? the center of rotation sufliciently far to cut" through the entire periphery oi! the orange 5 lnearer the center of rotation. The outer cutting edge 51 flares away at such an angle outwardly as to accommodate the outermost periphery of the orange 5|, carried over said knife i8 In oth 'e'r words the cutting edges 56 and 51 diverge from said piercing point 58 so that thefwidth of the knife where the orangeleaves it is wider than the normal diameter of thelargest orange to be used in said extractor. The curvatures oi the cutting,

edges 56 and 51 of the knife i8 are eccentric relatively to the center of rotation of the carrier:

l8, namely the inner cutting edge 55 curves to ward the center from the piercingpoint "while the outer cutting edge 51 curvesfrom said piercing point 58 outwardly and away from the center. of rotation. This particular shape of the knife causes eflicient shearing actionfor cutting the orange through the plane between the cups'23. The plane of the knife is aligned with the space between the cups 23. The knife I8 is securedin a suitablem'anner to the housing of the apparatus so as to be heldstationary relatively to the carrier mechanism l8, such asby means of a flange and screw 8|, or the like. f

The extracting mechanism 19 may be of any suitable type. In this illustration we provide a pair of spaced reamers 62 of the usual type, The spacing between the reamers 62. is the same as the distance between the cups 23 when held side by side in the same plane is's'hown in Fig.4 The rearners may be stationary or rotating. In this illustration rotation is transmitted to said reamers 62 by suitable gear transmissions; from a shaft 54. The reamers 62am locatedat the bot tom of the apparatus substantially symmetrically ffis l t h aver. v r

The

distance of each guide surface 22 from the center line of. the frame 29'varies'according to the width of the guideflange 14. This distance is predee termined so as tomove the lever arms 24 of the cups 23 in? oppositeadirections according to.-.-the

spacing or cup' position desired. At'about the portion A or the guidesurface-H the flange is sufliciently narrow to holds-the cup's 23 apart allowing them-to move over" the periphery of the fruit: 5] on :therloading. platform-53; vThis portion-ofthe pa-thior guide surface 22 between the point marked A and theloading platform 53 however gradually heightens,; :the flang Tit-being graduallywidened so as to force the cups; 23 toward eachother. At the point opposite the position of the fruit 5| on th platform}; the guide surface 22 vis high enough to causethe penetration 'ofthesharp pron s 28 into the orange 51. Thus the cups begin to'carry the orange ofi the loadingplatform 53. The'flangeis the widest nearthe topmost positionat about Bwhere the caps 23 are fully clamped onto the-orange 5|. It is to be noted that the guide surface'22 is such that. it never iorces they cups 23 into face to face contact. There is alwaysleft an annular space "between the cups 23 "in said clamping position. This space 16 is 1a a" central plane and the knife J8 ig aligned 'with it forcu'ttin'g through the r'nid guide flange 11 is 'all the juice that may escape through marked C below the knife l8. Beginning at the point C in approaching the extracting position the flange 14 gradually narrows until at about the points marked D the flange isso narrow that the springs 21- move the lever arms 24 to horizontally aligned positions in one plane as shown in Fig. 4. The cups are in this spread position during the aforedescribed reciprocating operation to and from the reamers l2. The guide surface 22 remains flat until the cups 23 pass the ejector actuator 2|. During the ejecting operationit is necessary that the cups 28 be prevented to yield to the force exerted ejector head 88. For this purpose a short parallel provided below each guide flange 14 radially opposite to the ejector actuator 2|. The flatly riding lever arms 24 are confined between the parallel flanges 14 and 11 during the rind ejection and are prevented from being folded by the ejecting force of the ejector parts of the cups 28. In this manner the position of the cups 28 throughout the cycle of operations in the apparatus is automatically determined so as to hold the fruit in the proper position for the various operations.

Under and around the reamers 82 is a suitable pan 18 which receives the extracted juice, collects it and dispenses it through a suitable spout 18. A screen 8| is extended across the spout opening 82 for straining the fruit juice. The .pulp and other substance collected on the screen 8| is cleaned by a reciprocating scraper 83 which is operated by an eccentric mechanism 84 from one of the reamer drives or transmissions 88. During the operation of the reamers 82 the scraper 88 agitates and scrapes the screen 8| of the juice from the apparatus.

The entire apparatus is included in a suitable housing which may be transparent if desired. The housing 88 herein shown compactly surrounds and protects the apparatus and it supports the stationary parts of the apparatus in their respective relative positions.

The hopper 48 is supported in the top of the housing 88 and the platform 58 is, supported on the discharge side of the hopper 48. The guide flanges 14 and 11 are supported on the inside faces of the sides of the housing 88. Suitable bearing' brackets 81 and 88 also extend from the sides of the housing 88 and the drive shaft 8| is rotatably supported in said brackets 81 and 88. The ejector actuators 2| extend parallel from the respective bearing brackets 81 and 88. The catch release abutment 42 extends upwardly from the bracket 81 near one side of the frame 28. The guide bracket 48 for the guide slot 44 extends upwardly from 88 near the opposite side of the frame 28. The reamer mechanism I8 is mounted on the bottom of the housing 88. The knife i8 is mounted on the curved wall 88 of the housing so that the lower edge and corner 88 of the knife I8 is proiected to incline and drip downwardly and into an extension 8| of the pan 18, thereby collecting during the cutting of the fruit.

In the heroin illustration the drive shaft 8| is driven by a motor 82 through a suitable gearing 93. A transmission, such as a pulley and chain or belt transmission 88 transmits power from the drive shaft 8|. to the reamer driving shaft 84 which latter is journaled beneath and outside the drain pan 18. A removable housin by the actuator 2| on theto assure flowthe bearing bracket- 2,818,818 the entire distances to about the point 1 8'8 incloses the transmissions and drives so that all moving parts are inclosed.

In operation the oranges drop down one by one from the hopper 48 into the platform 58 and rest there until picked up by the cups 23. Upon rotation of the drive shaft 8| thecups 28 are brought to the platform 58. The flanges 14 and guide surfaces 22 clamp the cups 28 over the orange or citrus fruit on the platform 53. The cups 28 are held in clamping position while they carry the orange over the knife l8 so asto cut the orange into halves. Then the guide surfaces 22 cause the parting of the cups 28 into the'horizontal level positions to register the cups 28 and the half oranges in them with the reamers 82. During the previous operation the shaft 8|, the eccentric disc 88 and the frame 28 rotated as a unit. At about the time when the cups 28 are separated and approach the location above the reamers 82, the outer arm of' the catch84 rides against the under side of the release abutment 42 and is tripped thereby so as to disconnect from the disc 33. At about the same time the guide pin 48 on the other side of the frame 28 abuts against the guide bracket 48 and then enters the guide slot 44. The disconnected frame 28 is reciprocated by the eccentric disc 88 so as to move the spread cups 23 against the reamers 82 and then back to normal position. At the completion of these strokes the disc hole 82 is aligned again with the catch 34 and the guide pin 43 is at the.

exit aperture 48 of the slot 44 so that the disc 88 and frame 28 again rotate as unit. The cups are then carried past the ejector actuator 2| and the rind is ejected as heretofore described. Then the cups 23 are again guided to clamping position and the cycle of operation is repeated.

While in the herein description of the operation of the apparatus reference is had to oranges and to extracting orange juice it is to be understood that the apparatus may be used with various citrus fruit and other fruits. There is fre-' quently a limiteddiiference in size of roundness of fruits within'the range of a grade used. The

methodfor allowing forslightdifierences in the sizes and shapes -'of the fruit "handled. In this modified form the cup 28' has a pair of diametri-' cally opposite wedge shaped slot 81 out thereinto. This. cup 28' is preferably made of sufliciently resilient material to allow; limited expan e sion. A coil spring band '88-'surroun'ds the cup 23" so as to urge the spl por ions of the cup 28' together.

It will be recognized that the apparatus herein.

efllciently and quickly extracts fruit juice." The device operates continuously while the shaft 8| is rotated. The shaft 8| may be rotated man ually, mechanically, and the device is adapted for coin control operation by regulating the rotation of theshaft 3| with a usual coin control mechanism. The device does not require any adjustment or setting up for each operation, because once adjusted it automatically picks up the fruit one by one, cuts the fruit, extracts and drains the juice, and discards the rind through a continuous cycle of operation 'eflicientiy within a compact unit.
